Ive got a hornady full length die and id like to take the neck diameter out a few thou and was wondering if anyone has had it done in oz?

Hmmmmm yeah I know its daym hard or I would have done it already! Haha
wonder if someone could do it with EDM?
My die is sizing them down to .310 so the inside of the die would probably be around .309 and ideally id like it to be about .314.
It just works the brass too much using the standard expander ball and even with proper mandrel it creates a fair bit of run out.

Alignment is the biggest issue with what method you use.
I'm sure a pin honing machine would get the job done.
EDM would do it also but the finish is not quite as good unless you use a lot of electrodes.
You can make a brass lap and flood it with something basic like JB Bore paste.
Something like a diamond coated drill bit might also do the job. Just remember the drills are spec'd out on the shaft diameter and do not include the coating thickness.

There are a number of tool and die engineering shops around also that should be able to handle a couple of thou in hardened tool steel or HSS. If you need to take more out look for a shop that handles tungsten carbide type tooling.

John
Wouldn't it be just as cost effective to buy a Redding Body Die instead or start with a die blank and have it heat treated...or is there something special you require from the die not readily available, just curious?

Not going to help your situation due to time constraints and is more just FYI but I just had a bushing FL Sizing die arrive in the post yesterday made by Whidden Gun Works in the USA. They made it up from the reamer print to save the dramas of sending cases in the post. Comes with a shoulder bump gauge as well. Took about 2 months which in the whole scheme of 'custom' isn't too bad I reckon.

keils,
pacific tool sell die blanks at a very good price.
for a bump die or body die you would not need any stems etc.
keep safe,
